What is Christmas 4 dogs? You do not have to be a student of mine in order to have a free run for your dog nor will you be recruited to be one.  If you're another trainer's student it does not matter.  You are limited to 1 free dog per person per family. If you have a dog that you like to work or a retired dog that would like a turn on sheep then bring it out.  It does not need to be a trained dog but should be socialized.  Multiple dogs per owner/family have a greatly reduced rate , after the first dog. Offer limited to available stock and day light hours. Christmas for dogs happens no matter the weather, sure the turn out is not as good on a rainy day but the closeness offered by the season is still there.
